The Telomeric Repeat-containing RNAs (TERRA) participate in the homeostasis of telomeres in higher eukaryotes. Here, we investigated the expression of TERRA in Leishmania spp. and Trypanosoma brucei and found evidences for its expression as a specific RNA class. The trypanosomatid TERRA are heterogeneous in size and partially polyadenylated. The levels of TERRA transcripts appear to be modulated through the life cycle in both trypanosomatids investigated, suggesting that TERRA play a stage-specific role in the life cycle of these early-branching eukaryotes.

Article Synopsis
  • Aplastic anemia (AA) is a condition that leads to low blood cell counts and is linked to issues with telomeres, which are protective caps on chromosomes.
  • A study of eleven AA patients between ages one and twelve revealed clinical symptoms like upper limb anomalies and short stature, alongside significantly shorter telomere lengths compared to healthy peers.
  • The research indicates that the telomere maintenance pathway is compromised in these patients, with treatments involving androgen and prednisolone reducing the levels of TERRA, suggesting a connection between telomere dysfunction and AA in younger patients.

Resveratrol (RSV) is a nutraceutical compound belonging to the nonflavonoid polyphenol family, whose antioxidants, anti-inflammatory, and antitumoral properties have been widely investigated. The ability of RSV to provide beneficial effects for neurological, cardiovascular, and cancer disorders rekindled the interest to explore the molecular mechanisms behind its pleiotropic effects, which are due to the modulation of coding and noncoding genes involved in many key biological pathways. With a computational approach, including docking studies and thermodynamics calculations followed by 200-ns-long molecular dynamics and a clustering analysis, we hypothesized the stabilizing binding between RSV and G4 structures of telomeric repeat-containing RNA (TERRA), which is a tumor-suppressive long noncoding RNAs (lncRNA) involved in the regulation of telomere maintenance.

Article Synopsis
  • RPA is a key protein that binds to single-stranded DNA and plays essential roles in DNA metabolism and telomere function.
  • It interacts with DNA to facilitate the replacement of other proteins during various cellular processes and is involved in managing G-quadruplexes at telomeres.
  • The study shows that hnRNPA1 can remodel the RPA complex at telomeres, while TERRA RNA can release hnRNPA1 from this complex, suggesting a specialized role in telomere protection.

Article Synopsis
  • Telomeres are protective DNA sequences at the ends of chromosomes that shorten during cell division, requiring the shelterin protein complex to maintain their stability and prevent genomic issues.
  • TERRA, a noncoding RNA derived from telomeres, is crucial for regulating telomere stability, and the hnRNPs, particularly hnRNPA1, interact with both TERRA and telomeric DNA, playing a role in telomere maintenance.
  • The study identifies how the UP1 domain of hnRNPA1 interacts with TERRA, revealing key residues involved and showing that this interaction is essential for hnRNPA1's function and droplet formation, which is important for maintaining genomic stability.

Telomeric RNAs, TERRA, as a Potential Biomarker for Spermatozoa Quality.

Article Synopsis
  • The study investigates the role of long non-coding telomeric repeat-containing RNAs as potential biomarkers for idiopathic male infertility, focusing on two groups of men: those with normal sperm (normozoospermic) and those with reduced sperm quality (oligoasthenozoospermic).
  • Findings reveal that oligoasthenozoospermic men not only had worse sperm quality but also produced embryos with lower inner-cell-mass quality, and they exhibited shorter telomeres and more sperm with abnormal telomeric structures compared to normozoospermic men.
  • A positive correlation was noted between telomeric RNA levels and sperm motility in normozoospermic men, suggesting
